There have been occasions where I would want to override a method in a class with an extension method. Is there any way to do that in C#? For example: public static class StringExtension { public static int GetHashCode(this string inStr) { return MyHash(inStr); } } A case where I've wanted to do this is to be abl...
Assuming the latest XCode and GCC, what is the proper way to override the memory allocation functions (I guess operator new/delete as well). The debugging memory allocators are too slow for a game, I just need some basic stats I can do myself with minimal impact. I know its easy in Linux due to the hooks, and this was trivial under code...
The Django documentation states the following clearly: Not every template in contrib\admin\templates\admin may be overridden per app or per model. It then lists the ones that can, and base.html, base_site.html and index.html – the ones I'm interested in – are not among those listed. They can be overridden per-project, but not per-a...
We have a class hierarchy which looks something like this: class base { }; class derived1 : protected base { private: float m_price; int m_quantity; float m_value; public: // float calculateValue(); }; class derived2 : protected base { private: double m_price; long m_quantity; double m_value; public: // doubl...
I'm trying to determine if the MethodInfo object that I get from a GetMethod call on a type instance is implemented by the type or by it's base. For example: Foo foo = new Foo(); MethodInfo methodInfo = foo.GetType().GetMethod("ToString",BindingFlags|Instance); the ToString method may be implemented in the Foo class or not. I want t...
When overriding a virtual method in Java, use of the @Override annotation is recommended, but what if I implement an abstract method? Should I use @Override then as well? ...
here is java code class Cup { public String sayColor() { return "i have a color ."; } } class TCup extends Cup{ public String sayColor(){ System.out.println(super.getClass().getName()); return super.sayColor()+"color is tee green."; } } class MyTCup extends TCup { public String sayColor(){ Syste...
I am trying to access a page that has certain javascript that causes errors and prevents the page from fully rendering. <script language="Javascript"> parent.hidden.vPageState = parent.hidden.NEW_LIST; </script> and <body onload="top.menu.activateCell(3);"> Both of these errors are related to the fact that I am accessing the page ...

If I have a HTML page that links to two stylesheets that are invoked like this: <link rel="stylesheet" href="original.css" media="screen, projection" /> <link rel="stylesheet" href="override.css" media="screen, projection" /> If these two files define the exact same style names, is it true that original.css will have no bearing on the...
I wanted to see that a dynamically loaded library (loaded with dlopen etc.) really uses its own new an delete operators and not these ones defined in the calling program. So I wrote the following library.cpp #include <exception> #include <new> #include <cstdlib> #include <cstdio> #include "base.hpp" void* operator new(size_t size) { st...
I'm replacing (overriding, improving, adding functionality to) a method in the prototype of the Date object. Here is a simplified version of what I've done: Date.prototype._toString = Date.prototype.toString; Date.prototype.toString = function(mask) { if(mask == undefined){return this._toString();} //snip //... //snip ...
Possible Duplicate: Why C# implements methods as non-virtual by default? I'm speaking primarily about C#, .NET 3.5, but wonder in general what the benefits are of not considering everything "virtual" - which is to say that a method called in an instance of a child class always executes the child-most version of that method. In ...
What would be some highly recommended books to get for a mid-level developer to learn advanced ASP.NET/C#/VB.NET techniques? Including, but not limited to, taking advantage of inheritance, when to use base pages, overriding base class methods, application architecture, interfaces, applying GOF design patterns in Web Applications, DAL, an...
I always wondered how to document a method that overrides a message from a base class. Normally I add a java doc to each public method and to some private, protected methods. But autogenerating a documentation block for an override method in eclipse produces something like this: /* * (non-Javadoc) * * @see javax.swing.JComponent...
I'm trying to override Object::Equals in C++ .NET but I'm running into some difficulties virtual bool IState::Equals(Object^ o) override{ if (o->GetType() == IState::typeid){ IState^ s = (IState^) o; if (s->type == this->type && s->target_state == this->target_state && s->current_state == this->current_sta...
I understand overriding a method/function redefines its implementation in the derived class from its implementation in the base class. Now what confuses me, is if I override a class in ASP.NET such as CreateChildControls() (I picked it randomly for no particular reason), VS2008 auto generates: protected override void CreateChildControl...
OK so I admit right off the top that this is a bit screwy … but it does serve a logical purpose. I’m using C# for a current project and I’m trying to find a way to override a member variable in a derived class, but access the overridden variable in a base class method. To make things more “entertaining” it would be preferable if the ov...
Hi everyone, I've uploaded a folder to a wordpress site. I'd like to access it e.g http://my.url.com/myfolder The problem is wordpress' .htaccess file which assumes I'm trying to load a page or post and doesn't load the folder. If you were in my boots, what would you do to overcome this situation? My .htaccess looks like so: Options...
I have this situation that when AbstractMethod method is invoked from ImplementClass I want to enforce that MustBeCalled method in the AbstractClass is invoked. I’ve never come across this situation before. Thank you! public abstract class AbstractClass { public abstract void AbstractMethod(); public void MustBeCalled() { ...
